Quaternary Period

This is the third and current period of the Cenozoic Era, as well as the Phanerozoic Eon.

This period brought many changes in the world. A glaciation event caused global temperatures to drop in the early Quaternary (or the Pleistocene Epoch).

Humans finally appeared in this period, and quickly became dominant over thousands of years. The world is as it looks today. Technology was featured in this period.

In the Mid-Quaternary (or Late Pleistocene-Early Holocene), an extinction event began, which is still going on today. It features the extinctions of various animals, such as the wooly mammoths, saber-toothed tigers, and various reptiles. This has been called the Quaternary (or Holocene) Extinction. Many of the extinctions have been caused by humans changing their habitat, and poaching. Many species are going endangered as well. This has sometimes been called the sixth mass extinction.
